Stuck Pixel Test
Attempt to fix stuck pixels by flashing colors rapidly (Epilepsy Warning).
Ready to Test?
Scan your screen on a black background to spot bright colored dots. Then cycle colors to confirm if the pixel changes at all.

What to look for?
Dead Pixels
Look for black spots on a white or colored background. These pixels are effectively "off" and don't light up.
Stuck Pixels
Look for bright dots (red, green, blue) on a black background. These are pixels "stuck" on a specific color.
What is stuck pixel fix?
A stuck pixel fix is a process designed to unstick pixels that are frozen on a single color (usually Red, Green, or Blue) due to a sub-pixel transistor malfunction. Unlike dead pixels which are black and often permanent, stuck pixels are 'always on' and can be distracting.
This tool uses a technique called 'pixel massaging' or 'epileptic flashing' where it rapidly cycles colors on the screen. This rapid change sends high-frequency signals to the liquid crystals or diodes, which can physically jolt the stuck sub-pixel back into its normal functioning state. While not guaranteed to work 100% of the time, it is the most effective non-invasive method for fixing stuck pixels at home.
How to use stuck pixel fix
- Step 1: Identify the location of the stuck pixel using our Dead Pixel Test.
- Step 2: Select the 'Static Noise' or 'RGB Cycling' mode.
- Step 3: Click 'Start Repair' to enter fullscreen.
- Step 4: Leave the tool running for at least 10-20 minutes. For stubborn pixels, you may need to run it for over an hour.
- Warning: This tool produces flashing lights. Do not use if you are photosensitive.
Frequently Asked Questions
Does this really work?
Yes, for many cases of *stuck* pixels, rapid color cycling can energize the pixel transistor enough to unstick it. It does not work for *dead* (black) pixels.
How long should I run it?
We recommend starting with 10-20 minutes. If the pixel remains stuck, you can try running it for 1-2 hours or even overnight.
